Hard to compare the 1151 and 3606 movements although they're nearly equal in functionality. Only for the 3606 I can confirm the chronometer certification, which just is a higher probability for accuracy. Depending on your lifestyle the higher rating of the 3222 for waterproofing could be useful. Finally I personally am a big fan of XXXX.80 (blue dials) where the 3222 with the matching blue bezel definitely is my visual favorite, whereas the crescent red date indicator of the 3523 is a nice and real distinctive feature.
Either are not at all a bad start for a collection, in my opinion. (I have seen new 3523.80 available through non-AD retail channels)
do share your final decision?
